PHI is the 21st letter of the Ancient Greek alphabet and symbolises balance, harmony and proportion. In a similar way, the third and fourth generations of the De Bortoli family are working together to create considered single vineyard wine that gives proportion to climate, soil and maker. Lusatia Park vineyard was first planted in 1985 and has been the source of some of the finest pinot noir and chardonnay made in the Yarra Valley.
